1 Claim.

This invention relates more specifically to an apparatus for preventing the formation of scale on the walls of the water jackets of internal combustion engines.

-Chemical analysis of water employed to cool the cylinders of explosive engines during their operation do not contain a sulficient quantity of chemicals that will hold the scale formation elements in solution especially when the cooling 10 water becomes unduly hot.

It is therefore an important object of this invention to co -mingle with the cooling water a percentage of the exhaust gases of the engine before its introduction into the water jackets of 15 the engine, whereby to chemicalize the Water to remove the scale from the water jacket walls, and to prevent its formation.

A further object is to provide an apparatus adapted to be connected with the explosion or 20 compression chambers and water circulating systems of internal combustion enginesin such a manner that a portion of the ignited charge will be co-mingled with the cooling water during each power stroke of the engine before the Water is introduced into the engine jackets.

Further objects and advantages will be apparent from the following description reference being had to the accompanying drawing, in which,

30 Fig. l is a side elevation of an internal combustion engine, showing my apparatus applied thereto.

Fig. 2 is a central vertical section of the jacketed gas admission means taken on line 22 of Figure 1.

Fig. 3 is a detail vertical section taken through the check valve.

Referring now more particularly to the accompanying drawing 5 indicates a general type of an 40 internal combustion engine of the stationary type commonly employed in manufacturing and oil field operations. Engine 5 consists of a cylinder 6, water jacket 7, and other usual and common mechanical elements whose description is not 45 thought necessary.

Cylinder 6 is provided on one side with a bore 8 and the jacket wall with a threaded opening 9, a short nipple i threadingly engaging the jacket opening 9 and its inner and seating in the cylin- 50 der wall, the bore 8 of the nipple being in alinement with the cylinder bore. Bolted or otherwise secured to the wall of the engine jacket 8, is a vertically disposed gas distributing member H, provided with a horizontal bore 12 in alinement 55 with the nipple bore 8, for discharging the exhaust gases from the engine cylinder into an enlarged chamber 13 in the bottom of member II. This chamber is provided with a screw operated valve I4 that serves to control the volume of gas from theengine cylinder into the vertical bore l of the gas distributing element H, a nut IE maintaining the valve in an adjusted position. The upper end i? of element 1! is externally threaded for the reception of a fitting 18, its upper portion being enlarged and having an internally threaded end into which is screwed the lower end of a tubular pipe l9 that forms a Water jacket, its upper end engaging a cross fitting 20. Secured in the bottom opening 2| of fitting is a vertically disposed gas discharge tube 22, its upper end having a reducing coupling 23 threadingly secured thereto. Mounted in the enlarged end of coupling 23 is a tube 24 of larger diameter than gas tube 22, in order to provide for expansion of the engine exhaust gases. Tube 24 passes through fitting 29 and packing gland-25, being bent downwardly, its lower end being connected to the fluid intake line 26 of a centrifugal pump 21 or the like. Line 26 is connected to a fluid cooling tank 28 at the bottom thereof. Interposed in the burned gas line 24 adjacent the pump 2'! is a check valve 0 of usual form, for preventing the cooling water. from entering the gas line on the operation of the circulatory system.

Connected to the pump discharge outlet is a pipe line M for delivering the cooling Water to the engine jacket as shown in Fig. 1, said line being provided with a by-pass line 32 for delivering cooling water to the water jacket of the gas line, the heated water from this jacket being discharged through a by-pass pipe line 33 into the main water dischargepipe line 34 connected to the engine jacket, its free discharge end being disposed above the water cooling tank 28, as clearly shown in the drawing.

By water jacketing the exhaust pipe line I9, the hot gases passing therethrough will not only be reduced in temperature but when they are discharged into the water intake line the cooled gases (carbon monoxide) will be immediately condensed to form carbonic acid, which w hen and thence downwardly through the check valve C into the intake line 26 of the pump where it is pump mounted. in the Water intake line, a water outlet pipe leading from the upper portion of the water jacket to the upper portion of the tank, the cylinder provided on one side with a bore and the jacket wall with a threaded bore, a nipple engaging the jacket bore and seating in the bore formed in the cylinder, a vertically disposed exhaust gas distributing member having a vertical bore secured to the wall of the engine jacket having a horizontal bore in alinement with said nipple bore, the juncture of the vertical and hori-' zontal bores of the distributing member being enlarged to form gas chamber, a valve means se- 7 cured tothe outer wall of the gas chamber for controlling the Volume gas from the engine cylinder to the distributing member, a gas discharge pipe connected to the upper end of the gas dis tributing member, its free end being connected to the water inlet end of the circulating pump, whereby the exhaust gases will be (to-mingled. with the water and chemicalize the same before its entry into engine water jacket.
